Thank you for the info! I will try and check under the car as soon as I can (guess it’s time to get some stands). And see about the speedometer cable.

I’ll check the sending unit for my fuel gauge. Should I replace the unit or see if it can be adjusted somehow?

I don't know. My Coronet the original was fine so I lucked out there. The Daughters Duster I bought a "reproduction" that was not the same. The originals had very long rods for the float any new one I have seen the arms are very short making them very sensitive. Her car works much like yours. You fill it up, it stays on full for some time then once it starts to drop it drips FAST to almost empty but there is still over 5 gallons in the tank. Someone makes an electronic box that goes in line with the sending unit that lets you make the resistance seem nonlinear to the gauge so you can calibrate what a sending unit that does not work right. My understanding is the original units the wiper winding were wound in a non linear manner and then aftermarket are wound in a linear manner because it is cheaper. Someday I need to figure it out.
